ROLLER-STOPPING MECHANISM FOR SPINNING-MACHINES.

EUTFICATION i'orming'part of Letters Patent No. 765,890, dated July 26,1904.

Application filed January 14, 1903. Serial No. 139,072. (No nodel.)

To all whom it may concern.-

Be it known that 1, JAMES HARRISON, aBritish subject, and a resident ofLongsight, Manchester, in the county of Lancaster, England, haveinvented certain new and useful Improvements in Apparatus for Spinning,Twisting, and Doubling Fibrous Materials, of which the following is aspecification.

This invention relates to apparatus for spinning, doubling, or windingyarns or threads,

its object being to prevent the thread or yarn when an end breakswrapping round the delivery-roller and also to prevent the broken endcoming into contact With the adjacent thread or yarn on either side ofit, and thus avoid doubles or flaws in the yarn consequent on a brokenend becoming twisted up with another.

The invention consists, essentially, in so constructing the machine thatthe top deliveryroller will on the breaking of the yarn fall from itsposition into a suitable receptacle and there grip or secure the brokenend of yarn, so that it can neither lap upon the rollers or engage orbecome entangled or doubled upon an adjacent end or thread of yarn.

The invention will be fully described with reference to the annexeddrawings, in which it is shown applied to a doubling-frame, sufficientof the head of the machine being shown to illustrate the invention.

Figure 1 is a transverse sectional elevation through the drawing-head;Fig. 2, afront elevation of same; Fig. 8, atransverse sectionalelevation showing arrangement for applying the invention to existingdrawing-heads; Fig. 4, a transverse sectional elevation showing theinvention applied to another formation of stand; Fig. 5, a sideelevation, partly in section, showing roller-stand A and swing-loop B;Fig. 6, a front elevation of Fig. 5; Fig. 7 'a side elevation, partly insection, showing another form of swing-loop B; Fig. 8,a front elevationof Fig. 7 Fig. 9, aside elevation, partly in section, showing a modifiedform of roller-support A and swing-loop B; Fig. 10, afront elevation ofFig. 9; Fig. 11, a sectional plan on linear m, Fig. 7; Fig. 12, atransverse sectional elevation, showing another form of stand; Fig. 13,a side elevation of another form of swingloop E, which falls with rollerB; Fig. 14, a front elevation of Fig. 13.

The top roller R and the bottom roller R and the other parts of themachine either for drawing, doubling, twisting, or spinning are of anyordinary construction.

The bottom roller R is supported in the bearing a of the roller-stand A,but the top roller R is supported upon the bottom roller R by a nib orsupporting-bracket D, placed at the front side only of the roller,against which the roller journals 7- rest, leaving the roller R free tofall off at the back.

The roller-stand A is made with an arm a projecting over to the frontside to provide a support for a nib-bar or top roller-support D. The baror support D is secured to the rollerstand arm a by screws and hangsdown in front of the journals 7* of the top roller R.

The top roller R is set a suitable distance toward the front over thecenter of the bottom roller R to cause it to retain its position as itrotates. The pivots or journals r of the top roller R rest against thenibs d of the bar D by reason of the weight of the roller.

Above the top roller R a swinging loop E, of light wire, is pivoted,which hangs in front of the top roller R and is held out of contact withit by the resting upon yarn or thread T. The swinging loop is pivoted orhinged in any suitable way either between two bars D or in a bearing Dand is formed with yarn guide or eye d along one edge. It rests upon theyarn T as it passes from the rollers R and R to the thread guide orspindle, (not shown,) and should the yarn break it falls and engages thetop roller R, lifting it from its position 015? the bottom roller R andcausing it to fall down behind. The lightwire loop E when it falls bythe breaking of the thread either engages the peripheraledges of the toproller R and the frictional resistance caused thereby forces the rollerbackward or the lower edge is drawn in between the nip of the tworollers and dislodges the top one. The light swinging loop E may bepivoted to the journal 1' of the top roller R, as in Figs. 13 and 14,and the supporting-bar D may be affixed to the stand to project upbetween the two rollers, as in Fig. 12.

Behind the bottom roller R a receptacle G is constructed to receive thetop roller R when it falls and hold it fast. The receptacle G is of
